Product Description Integrated vortex flowmeterIntegrated vortex flowmeter with temperature and pressure compensation, mainly used for flow measurement of industrial pipeline media fluids, such as gas, liquid, vapor and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. This instrument uses piezoelectric stress sensors with high reliability and can operate within a temperature range of -20 oC to+250 oC. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal flow rate.As can be seen from the above equation, the pulse frequency signal output by VSF is not affected by fluid properties and composition changes, that is, the instrument coefficient is only related to the shape and size of the vortex generator and pipeline within a certain Reynolds number range. However, as a flowmeter in material balance and energy measurement, it is necessary to detect mass flow rate. At this time, the output signal of the flowmeter should simultaneously monitor volume flow rate and fluid density. Fluid properties and components still have a direct impact on flow measurement.The vortex flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure standard volumetric flow rate and mass flow rate, making it an ideal alternative to throttling flow meters.In practical applications, the maximum flow rate is often much lower than the upper limit of the instrument, and with changes in load, the minimum flow rate is often lower than the lower limit of the instrument. The instrument is not working in its optimal working range. To solve this problem, it is usually necessary to reduce the diameter at the measuring point to increase the flow rate at the measuring point, and use smaller diameter instruments to facilitate the measurement of the instrument. However, this variable diameter method requires a straight pipe section with a length of more than 15D between the variable diameter pipe and the instrument for rectification, which makes processing and installation inconvenient. The LGZ variable diameter rectifier with a curved longitudinal section has multiple functions such as rectification, increasing flow velocity, and changing flow velocity distribution. Its structural size is small, only one-third of the inner diameter of the process pipe, and it is integrated with the vortex flowmeter. It not only does not require an additional straight pipe section, but also reduces the requirements for the straight pipe section of the process pipe, making installation very convenient.For the convenience of use, the battery powered local display vortex flowmeter adopts low-power high-tech. It can operate continuously for more than a year with lithium battery power supply, saving the procurement and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. on site. The temperature compensated integrated vortex flowmeter also comes with a temperature sensor, which can directly measure the temperature of saturated steam and calculate the pressure, thereby displaying the mass flow rate of saturated steam. The temperature pressure compensation integrated type is equipped with temperature and pressure sensors, which can directly measure the temperature and pressure of the gas medium for gas flow measurement, thereby displaying the standard volume flow rate of the gas.main features 1.

External power supply+24VDC ± 10%working principleThe principle of vortex flowmeter: By setting a triangular cylindrical vortex generator in the fluid, regular vortices are alternately generated from both sides of the vortex generator, which is called Karman vortex.The vortex flowmeter applies the principle of fluid oscillation to measure flow rate. When the fluid passes through the vortex flowmeter in the pipeline, two columns of vortices proportional to the flow velocity are alternately generated up and down behind the vortex generator in the triangular column. The release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator.The integrated vortex flowmeter is a new type of flowmeter for measuring fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure standard volumetric flow rate and mass flow rate, making it an ideal alternative to throttling flow meters. In order to improve the high temperature resistance and vibration resistance of vortex flow meters, our company has recently developed the HLUG improved vortex flow sensor. Due to its unique structure and material selection, the sensor can be used in harsh working conditions such as high temperature (350 oC) and strong vibration (≤ 1g). In practical applications, the maximum flow rate is often much lower than the upper limit of the instrument, and with changes in load, the minimum flow rate is often lower than the lower limit of the instrument. The instrument is not working in its optimal working range. To solve this problem, it is usually necessary to reduce the diameter at the measuring point to increase the flow rate at the measuring point, and use smaller diameter instruments to facilitate the measurement of the instrument.
